COMBINED REFRIGERATOR AND WATER-COOLER.

SPECIFICATION forming part of Letters Patent No. 486,286, dated November 15, 1892.

Application filed July 5, 1890.

To aZZ whom it may concern:

Be it known that I, MICHAEL GREENEBAUM, a citizen of the United States, residing at Chicago, in the county of Cook and State of Illinois, have invented a new and useful Im provement in a Combined Refrigeratorand Tater-Cooler, of which the following is a specification.

My invention relates to certain improve- 1o ments upon the combined refrigerators and Water-coolers for which Letters Patent of the United States Nos. 211,565 and 238,679 Were granted to me, respectively, January 2l, 1879, and March 8, 1881.

The features of construction which constitute my present improvements will be made clear by the following description, reference being had to the accompanying drawings, in Which- Figure 1 is a central Vertical section of my device, and Fig. 2 a vertical section taken on the line 2 2 of Fig. 1 and viewed inthe direction of the arrow.

My present device omits the filter, which V formed one of the features in the devices which formed the subjects of my Letters Patent aforesaidybut this omission has nothing to do with my present invention, which relates entirely to features of construc- 3o tion designed to contribute to the efficiency of the apparatus both as a refrigerator for L ggeneral domestic purposes and as a watercooler, andif it is desired to combine with these a filter this may as easily be Vdone with 3 5 this apparatus, as in the oase of the appara'i ratuses described in my former patents.

In the drawings, A represents the chest, which may be divided into compartments, according to requirement, and may be lined 4o with metal or not, as preferred, and may be made either with single walls, as shown, or with filled or spaced double Walls in any of the common and well-known ways, since the construction and arrangement of the chest itself forms no part of my present invention.

B is a daring pan having a large openingt through its center, and which is supported from the inner walls of the chest by means of brackets s. This pan performs the twofold 5o office of a detlector for the chilled air in its descent, causing 'it to circulate in the proper direction, and of a purifier of the air by precipitating the moist impurities and causing them to flow out of the refrigerator by Way of the drainage-pipes, as will appear further on, and it also aids in supporting the parts above it. Maintained above the bottom of the pan B by means of radial supports fr is a pan' C, somewhat less in diameter than the pan B. Within the chest and supported from the walls thereof by means of brackets q is a reservoir D, preferably cylindrical, so that it mayy easily withstand any hydrant-pressure to which it may be subjected. Into thetop of this reservoir a pipe p leads from the Water-supply, and a separate pipe o, in the formof a dip-pipe, leads from near the center of the reservoir up through the top, and over to the bottom of the pan C, where it is formed.'

ward by the continuation o2 to the faucet n. 1

The purpose of having the pipe o pass up from near the center of the reservoir is to take the water from a point where it will be most free from both the lighter and heavier impurities. reservoirs within the same refrigerator, each having its own cooling-coil leading to a separate faucet, so that other beverages-as tea and coffee, for example-may also be cooled.

Leading through the bottom of the pan C and extending considerably above the upper surface of the coil o', as shown, is an overflow-pipe m, which leads out through the Wall of the chest and down into the trap E, which is secured to the outer wall of the chest over the sink'F'Inpractice I support the sink from its upper side tlangesmpon brackets. (Not shown.) The trap E comprises a receptacle Z for Water, into which the lower end of the pipe m dips, and an overflow le, extending downward into the sink.

In some cases I provide additional Supported upon the bottom of the pan C is the ice-support G, which consists of a fiat metal plate braced across its center by a rib t' and mounted upon a series of legs h, each braced by a web g, and it is preferable to inclose thek ice within four metal walls having openings through them at their bases for the exit of the chilled air, the front wall being removable to give access for the insertion of ice. I make these Walls of sheet-1n etal plates H, reinforced by strips f and provided with legs e, which fit IOO within the edges ofthe pan C and which are made long enough to extend from the bottom of the pan sufficiently above its top to afford the openings d.

Below the pan B and supported from the walls of the chest, as by metal strips c, is an inclined curved or synclinal pan J, provided with a drainage-pipe m', leading through the wall of the chest into the overiow-pipe m, and upon this pan is a pan K of similar form, but smaller` and inverted, the purpose of which is to present a surface above the pan I for the condensation of moisture, so that the lower Asurface of that pan shall remain comparathe water-supply and the reservoir through the pipe p. The faucet n being opened fora brief period to expel the air, the coil 0 becomes filled with water. meliug ice soon submerges the coil, so that the water therein in a short time becomes reduced to a temperature corresponding with that of the melted ice, and the drip thus collected materially aids toward cooling the interior of the chest. The situation of the reservoir within the refrigerator is productive of decided advantage, since it causes the water to be considerably reduced in temperature before it enters the coil. As fast as the water from the inciting ice attains the level of the top of the pipe m it tiows olf through that pipe to the trap E, whence it passes olf to the sink and thence to the sewer or any receptacle provided for it. The purpose of the trap E is to prevent any backfiow of air into the interior of the chest.

As a result of the construction of condensing-surfaces, deliecting-surfaces, and drainage-pipes described above, a continuous circulation of cold dry air is maintained throughout the refrigerator, and all atmospheric impurities and effluvia are immediately carried olf through the drainage-pipes, causing the interior with ordinary care always to remain pure and wholesome. The principal downward current is through the ice-inclosure in direct contact with the ice, thence through the openings CZ at the base, thence between the pans B and C, through the opening t, and

The drip from the over the pans I and J`, displacing in its progress warmer air, which finds its way to the top and is in its turn chilled and precipitated, thus maintaininga constant circulation, during which the air is continuously subjected to the purifying and moisture-condensing inuences of the devices for these purposes described above.

W'hat I claim as new, and desire to secure by Letters Patent, is

l. In combination with the refrigeratorchest A, the pan C, supported within the chest, reservoir D, supported within the chest and provided with a pipe p to connect it with a water-supply, coil 0' in the pan C, continued at one end into a pipe o, passing into the interior of the reservoir D near the center thereof and continued at the other end into a pipe o2, leading to the faucet n, an ice-support above the pan C, and an overflow-pipe extending from a point above the coil o through the pan C and out of the refrigerator, substantially as described.

2. In combination with the refrigeratorchest A, pan C, supported therein, coil o within the pan (l, communicating at one end with the water-.supply and at the other `with the faucet n, ice-support above the pan C, overtiow-pi pe leading from a point above the coil o through the pan C and out of the refrigerator, and flaring pan B, having the opening t and within which the pan Cis supported, the drip-receiving pan I, supported below the pan B and provided with a discharge-pipe m', leading out ofthe refrigerator, and condens ing-pan K,inverted upon the pan I, substantially as described.

3. In combination with the refrigeratorchest A, pan C, supported therein, coil o within the pan C, communicating at one end with the water-supply and at the other with the faucet n, overliow-ppe leading from a point above the coil o through the pan C and out of the refrigerator, flaring pan B, having the opening t and Within which the pan C is supported, ice-support G, and the inclosure for the ice, comprising plates I-I, supported above the edges of the pan C and having spaces d below them, substantially as described.
